Note
Please don’t email us personal payslip data — your name, personal ID number, or exact amounts. A sample is enough for a rough estimate. The site has no account, no sign-up and no form that would collect personal data — this email is the only way to reach us. Google Analytics 4 does run on every page of the site, though, without cookies; what Google receives from that is explained on the Privacy page.
